Learn Italian: Questo sondaggio è interessante, ne scriverò sul giornale. - This poll is interesting, I will write about it in the newspaper.

The pronoun ne replaces phrases that start with di (of/about). The verb scrivere takes the preposition di when you write about something (scrivere di qualcosa). So, to say "I will write about it," you replace the implied di questo sondaggio with ne.

Why does ne go before the verb scriverò instead of attaching to the end of it?

Pronouns like ne only attach to the end of infinitives, gerunds, and imperatives. Because scriverò is a conjugated verb (in the future tense), the pronoun must be placed immediately before it.

Why does the Italian use sul giornale when the English translation says "in the newspaper"?

While English says you write something "in" a newspaper, Italian treats physical printed media like newspapers and magazines as surfaces. Therefore, it uses the preposition su (on). Combined with the definite article il, it forms the articulated preposition sul.

How do we know scriverò is in the future tense just by looking at it?

The accented -ò ending is the standard first-person singular (io) ending for regular verbs in the future tense. The accent mark is mandatory because it tells you to stress that final syllable when speaking.
